IMPROVEMENT' IN LANTERNS.

To (LU who/2t it www concern,.-

e it known that l, Frites DEAN, of Buffalo, inthe county ol- 'llrief andState of New- York, have invented a new and useful Coinbined SignalLantern' and Lamp; and I do hereby declare the`f`ollowing` tobe a full,clear, and exact description of the same, reference being had to the:'iccompanying drawings, which are inade part of this specification, andof which- Figure l is sectional side elevation of a lanternillustrating-.my invention. Fig. .Zis a side elevation ofthe same.

, Similar letters of reference indicate corresponding pa'rts in the twofigures.

The subject of this invention is-niore particularly intended for use asa signal-lantern for railroad-cars, but may be employed as adark-lantern, or have some ot` the parts detached, and then constitute acommon illuniinating-lanip for domestic or other use.

'lhc invention also includes a match-lighting` device, which enables aperson to light the lamp in the open air without exposing the ignitedmatch to danger of extinguislunent by the wind. x

A may represent a lamp of any suitable construction. rlhis lamp isprovided with an annular` flange, B, upon which rest the cylin- -driealglass and casing, which, as associated with the lamp, constitute eithera signal or a dark lantern.

The lantern-glass C is fixed in position by means of a bottoni fla-nge,c, and upright rods 7i., said rods being fixed at top to an lannulus, l,in the center of which isinserted a cap-covered tube, J. A metalliccylinder, D', encircles the upper part of the rods l1, and isi`1nmovable thereon.

l) is u movable cylindrical shield, which is fitted to slide upon thecylinder D' and-upon the lower ends of the rods h. A bent rod, D2, ismade fast to the sliding shield D, so as to form a bail or handle,whereby the shield I) may be elevated or depressed, in order to eitherexpose or entirely inelose the glass C,

and thus diffuse the light, or wholly obscure the saine. At oppositesides ofthe sliding shield l) are circular openings, in which glasses ofdifferent color-say red and blue--may be inserted, as at D, Thesecolored glasses may be guarded by hinged doors, so as to permit no lightto esca-pe when the slide D is de pressed; 'but for signaling purposeseither of these glasses may be exposed by opening` its door when theslide is depressed, as aforesaid. It will thusbe seen that by means of'the sliding shield 1),' constructed and applied to the lantern-case asdescribed, the device may be used' as a signal-lantern or adark-lautern, and that it may be luade to afford 'a whiteef't'ectively-illuminating light when not used for signaling. rlheflange B heilig coupled with the flange c by means of' spring-clasps,the lantern-case, including the glass C, the sliding shield l), cylinderD', rods h, Sie., may be readily detached from the lamp A, which, withits chimney A', may be then used as an ordinary illuminating. domesticlamp.

XVhen the lamp is combined with the lantern, as hereinbef'ore described,the lampchimney A is inclosed by the lantern-glass U, a space existingbetween the two spaces to conduct the air downward from the top of' thelantern to supply the fiani'e. No air is admit ted from. below. Thepassage ofthe air downward to the Haine audits exit upward through 4thechimney A' and cap-covered tube J are indicated by the arrows in Fig. l.

A cup for heating water or other similar purpose may. be substituted forythe part J, suitable provision being niadein that ease to admit of theescape of the products. of conibnstion in an upward direction.

. E is a tube extending Oblitlucly upward through the flange B of thelamp, and termi nating at a point in proximity with the up# per end ofthe wick-tube. The upper termi'- nus of said tube is closedby a pivotedfinger, F, whose surface may be roughened or in any' way adapted toinsure the ignition of a match when the saniefinay be inserted throughthe tube and made to push the finger away from the upper mouth of thetube.A The finger is made to offer a sufiicient resistance to the thrustof the match by a spring applied in any suitable manner, said springserving also to restore the finger to its normal position after thematch' has been withdrawn.

It is manifest that, inasnnich as the upper end of the tube E and fingerF are inelosed within thelantern glass or casi ng. the wick 'may beignited in the open air by a match passed upward through the tube E,notwithstanding the prevalence of strong winds.
